ethanol from sugar beet [9,14]. Studies on the continuous ethanol fermentation of these intermediates are still rare, although Vucurovic et al. [15] reported a continuous ethanol fermentation process of thick juice by immobilizing yeast cells onto sugar beet pulp. However, to the best of our knowledge, there is still no report on the continuous ethanol fermentation of the raw juice and thick juice using flocculating yeast strain. In this study, a flocculating yeast Saccharomyces cerevisiae strain KF-7 was used to establish the continuous ethanol fermentation processes to convert the raw juice and thick juice of sugar beet to ethanol and to achieve high ethanol yield, ethanol concentration and productivity.
